Yes but fewer calories might also make you less productive at work. Might affect your reasoning and executive skills. They might also reduce your sex drive.
Not sure maximum age is what you want to optimize for unless there is more data.

Fewer calories doesn't mean starvation. We have evidence time-restricted feeding decreses fat mass without compromising musculature or strength while reducing inflammation [1]. Curiously, while "resting energy expenditure was unchanged," basal metabolism did go down.
I don't think the solution is everyone time-restricting their feeding. But there is something here that suggests a broad quality-of-life improvement for many Americans.
REE was the proxy for basal metabolism. They measured respiratory ratio which decreased, but that's not BM just (should) reflect what macros are being burned
Of course this is only for optimizing - not relevant for almost anyone except elite athletes, I believe.
If one is actively working on building muscles there's already a pretty concerted effort to the whole goal, adding some protein supplement to that is much easier than carefully planning your breakfast, lunch, dinner, and snacks to reach your daily intake needs.
There is also a limit to the rate at which you can assimilate amino acids which is why all things being equal spacing out the protein throughout the day is more optimal.
I understand your point but it feels to me a little bit of soapboxing.
Being more optimal only really matters at a very high level of athleticism goals, if one is at the point where they need to optimise their protein intake windows they'd already know about it given that reaching such high level requires a lot of nutrition knowledge.
I'm stating this because there's a tendency on Hacker News comments to overoptimise everything. Yes, there are optimal ways that can give an edge for people requiring that edge but most people here are just normal people who shouldn't at all be caring about that, the tendency to min-maxing will just become an obstacle.
It's not just about anabolic window timing though. In fact, my point in using the word optimal is about the opposite of how you are approaching it above. For the majority of HN audience that fall outside of the switched-on bodybuilder/diet planning over-optimiser type, a restrictive TRF window simply makes it more difficult to get all the protein that one could benefit from. I'm not talking about optimising to the point of diminishing returns; the simple heuristic "don't skip breakfast but have one with protein" can have a significant benefit to the dietary macronutrient composition for many people with no other effort. Because even if they know two scoops of whey after or eating a second chicken breast for dinner might be a good idea, it doesn't always happen because there are more hedonic choices.
1g of olive oil will give you around 9kcal, when I used to track all my daily intake it was around 100+kcal for a tablespoon of olive oil. Peanut/other nuts butter provide a little less calories per gram but add protein to the mix.
